Process of breeding & delivering staple crops
that are naturally
enriched with micronutrients
It all starts with a seed.

Biofortification
Biofortification – the Evidence
— Breeding increases nutrient levels without reducing yield
‒ Farmers are growing biofortified crops, and consumers are eating them
— Extra nutrients in crops improve micronutrient status
— Biofortification is cost-effective

Biofortification Priority Index (BPI)
— It is a tool to help stakeholders assess where, and in which biofortified crops to invest
— It ranks 127 countries globally
— 3 regions: Africa, Asia, and LAC
— National level data sources:
— Production & consumption: FAO 2010
— Micronutrient deficiencies: WHO and IZincG
Priority Conditions
Production Index (PI) = [1 – export share] x [ ½ (Per capita area harvested) + ½ (% land area allocated to crop )]
Consumption Index (CI)= Consumption per capita x (1-Import Share*)
*Import share = Imp/(Pdn + Imp - Exp)
Vitamin A Deficiency Index = ½ [Prop children with retinol < 0.70 umol/l] + ½ [Age-standardized DALYs]
Iron Deficiency Index = ½ [Prop children with Hb < 110 g/l] + ½ [Age-standardized DALYs]
Zinc Deficiency Index = ½ [% population at risk of inadequate zinc intake] + ½ [Prevalence of stunting]
Production Index (PI) = [1 – export share] x [ ½ (Per capita area
harvested) + ½ (% land area allocated to crop )]
Consumption Index (CI)= Consumption per capita x (1-Import Share*)
*Import share = Imp/(Pdn + Imp - Exp)
Vitamin A Deficiency Index = ½ [Prop children with retinol < 0.70 umol/l]
+ ½ [Age-standardized DALYs]
Iron Deficiency Index = ½ [Prop children with Hb < 110 g/l]
+ ½ [Age-standardized DALYs]
Zinc Deficiency Index = ½ [% population at risk of inadequate zinc intake]
+ ½ [Prevalence of stunting]
BPI
Ethiopian Subnational BPI
Production Index (PI) = ½ [Per capita area harvested]r + ½ [Agricultural land allocated to the crop]r
Consumption Index (CI)= [Consumption per capita]r
Vitamin A Deficiency Index = ⅓ [100 - Food rich in vitamin A] +
⅓ [Prevalence diarrhea] + ⅓ [Night blindness during pregnancy]
Iron Deficiency Index = ⅓ [⅓ (IDA moderate and severe women) + ⅓ (100 - Iron supplements women) + ⅓ (100 - Iron
supplement children)] + ⅓ [IDA moderate and severe children] + ⅓ [100 - Food rich in iron]
Zinc Deficiency Index = ½ [100 - % children who consumed foods rich in iron in last 24 hours] +
½ [Stunting prevalence]
Concluding remarks
— Global BPI
— Ethiopia is a prime country for biofortification of Vitamin A Maize Zinc Wheat Iron Pearl Millet Vitamin A Sweet Potato
— Ethiopian Subnational BPI
— Vitamin A Maize: Zones in Amhara and Oromia
— Zinc Wheat: Zones in Amhara, Oromia, Tigray and SNNP
